Summary: Recently, the use of sodium percarbonate (SPC) as a substitute for H2O2 in advanced oxidation processes has gained significant attention. This study investigated the degradation kinetics and mechanisms of antibiotic sulfamethoxazole (SMX) using UV-driven SPC system. It was found that the removal efficiency of SMX increased with higher dosages of SPC. Scavenger experiments confirmed the presence of hydroxyl radical (center dot OH), carbonate radical (CO3 center dot-), and superoxide radical (O-2(center dot-)), with center dot OH and CO3 center dot- playing a significant role in SMX degradation. The presence of anions and natural organic matters affected the reactions mediated by these radicals, suggesting incomplete mineralization of SMX is common. Four intermediates and transformation patterns of SMX were identified through DFT analysis. Metabolomic analysis showed decreased negative effects in E. coli after 24 hours of exposure to intermediates, indicating a reduced environmental risk of SMX. This study provides valuable insights into the biological impacts of SMX and its transformation products, as well as guidance for SMX pollution control using UV/SPC technology.

Summary: The combination of sodium percarbonate (SPC) and ozone (O-3) was effective in enhancing the elimination of sulfamethoxazole (SMX) in water, with alkaline conditions showing the best removal efficiency. Free radicals, especially (OH)•, played a crucial role in the decomposition of SMX, and the addition of SPC promoted the production of (OH)• in the O-3 system, leading to improved elimination of SMX. The degradation of SMX and the enhancement of TOC and COD removal were observed in the O-3/SPC system, indicating the potential of this method for water treatment.

Summary: The study developed Fe-rich sludge biochar (Fe-BC) activated by sodium percarbonate (SPC) for efficient removal of sulfamethoxazole (SMX) from swine farming wastewater. The Fe-BC/SPC process achieved highly efficient SMX degradation within 5 min, with kobs of 1.1439 min(-1). The main mechanisms involved adsorption and oxidation processes, with SMX likely being adsorbed on the Fe-BC surface and degradation pathways including hydroxylation, -NH2 group oxidation, O-N bond cleavage and N-S bond cleavage reactions. The Fe-BC/SPC process showed high SMX removal performance and low toxicity. Overall, Fe-BC/SPC is a promising and efficient system for SMX degradation in swine farming wastewater treatment.

Summary: In this study, a Fe-doped g-C3N5 (Fe@g-C3N5) photocatalyst was synthesized for the degradation of tetracycline hydrochloride (TH) and Naproxen (NPX) using Peroxydisulfate (PDS) based advanced oxidation processes (AOPs). The Fe@g-C3N5 showed higher photocatalytic performance compared to g-C3N5 and g-C3N4, with a 19% and 67% degradation enhancement for TH at pH 3, and 21% and 35% at pH 7. The FeN4 structure formed by the doped Fe atom improved the charge separation capacity of g-C3N5 and acted as a new reaction center for efficient PDS catalysis. Despite weak intrinsic photo-degradation performance, Fe@g-C3N5 has great potential for improvement and application in wastewater treatment.

Summary: This paper summarizes the positive effects of biochar on microorganisms in soil bioremediation, including acting as a shelter, providing nutrients, and improving soil conditions. These effects result in variations in microbial abundance, activity, and community structure. Biochar also acts as an electron mediator to promote electron transfer in microbial degradation. However, the potential toxic substances carried by biochar that can threaten microbial communities should not be overlooked. This review helps us better understand the role of biochar in soil bioremediation and enables targeted selection and modification of biochar for desired outcomes in practical applications.
